Japan secures the first asteroid soil… Will the Earth be the secret pool clue
[앵커]
Sand, which had been sleeping for 4 billion years, arrived from an asteroid about 13,500 times the distance between the Earth and the Moon.
Japanese space probe Hayabusa 2 succeeded in sending soil samples to Earth.
It is noteworthy whether it can be a clue to solving the secret of the birth of the Earth.

A red fireball falls into the night sky in the desert in southern Australia.
It is a separate capsule from the Japanese asteroid probe Hayabusa 2.
When the news that the capsules of Hayabusa 2 have been safely settled, Japanese control centers are cheering.
The Japanese citizens who watched through the broadcast are also excited.
“I’m so happy to land successfully. My heart was beating faster when I was watching (watching).”
Hayabusa 2 was the first mankind to secure soil that had been asleep for about 4 billion years under the surface of the asteroid’Ryugu’.
This is one step further from what Hayabusa 1 previously sampled from the asteroid’s surface.
The capsule, which Hayabusa 2 flew to Earth after a 5.2 billion km flight, contained about 0.1 g of sample.
Unlike the material on the surface, the soil beneath the surface is highly likely to be unaffected by weathering, so it is expected that it could be a clue to the question of the secret of the earth’s birth or the origin of life.
A research team from the Japan Aerospace Research and Development Organization (JAXA) retrieved this capsule containing sand from the asteroid’Ryugu’ and went into analysis.
“We look forward to seeing how the solar system formed and how water entered Earth through sample analysis of the asteroid’Ryugu’.”
Meanwhile, China’s unmanned lunar probe’Changeo 5’also succeeded in obtaining samples of the lunar surface.
China’s state-run Xinhua News Agency said that this is the first time that the Changeo 5 has successfully docked with the return ship and that a Chinese spacecraft has successfully docked in lunar orbit.
